Answer is E
Since if we reduce give condition further down we will get m^k=m^k^2
1) If m = 2 then k can either be 0 or 1 but using these two values we will get m^k as 2 or 1 hence, not sufficient 2) if k is not equal to 2, in this case value of m is unknown m can take any value plus k can any value apart from 2. Not sufficient
Both statement together doesn't provide much info.
Hence, answer E
